Vector charts provide many advantages over traditional raster charts. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. are all selectable and have real time distance, bearing and detail information. Turn off layers to de-clutter the display and only show what is important at the time. Tides, moon and sun times and weather are also all available at your fingertips.
In-app tools let you measure distances and bearings and record waypoints on routes to sail. When you are out at sea, the app’s Sailing HUD shows your position on the route, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. Waypoint reached alerts, auto-routing to the next waypoint and flashing collision alerts (with AIS).
Unique AR view mode (IAP) allows you to view buoys, lights, ships, waypoints, route and track overlaid on your iPhone or iPad live camera view. With "AR LockOn" you can select a target on the chart and then be guided to it in the AR camera view. You can also see at night and in the fog with the FLIRONE Infra-red camera.
